(57) A wireless communication method for recovering information bits from a received signal, implemented by a wireless communication receiver, comprising: receiving, over a communication channel, a wireless signal comprising a data signal portion and a pilot signal portion wherein the pilot signal portion includes multiple pilot signals multiplexed together in an orthogonal time frequency space, OTFS, domain; transforming the wireless signal into a delay-Doppler domain signal by applying a two-dimensional symplectic Fourier transform; applying a delay-Doppler domain mask to separate out a contribution of each of the multiple pilot signals to time-frequency domain signal into corresponding separate received pilot signal contributions; estimating, using the separate received pilot signal contributions, the communication channel estimates at delay-Doppler domain positions of the multiple pilot signals; and interpolating the communication channel estimates to obtain an entire communication channel estimate.
